Abstract (en)
An ESD protection device whose ESD characteristics are easily adjusted and stabilized is provided. An ESD protection device 10 includes (a) a ceramic multilayer substrate 12, (b) at least a pair of discharge electrodes 16 and 18 formed in the ceramic multilayer substrate 12 and facing each other with a space 15 disposed therebetween, and (c) external electrodes formed on a surface of the ceramic multilayer substrate 12 and connected to the discharge electrodes 16 and 18. The ESD protection device 10 includes a supporting electrode 14 disposed in a region that connects the pair of discharge electrodes 16 and 18. The supporting electrode 14 is obtained by dispersing a conductive material 34 coated with an inorganic material having no conductivity.
